Subject: use sync to ensure file written to sd card
X-Git-Url: http://challenge-bot.com/repos/?p=challenge-bot;a=commitdiff_plain;h=17359f928d9afe94c74008af8dd438280dd9c998

use sync to ensure file written to sd card

rather than rely on just waiting for 1 second, use sync to ensure
that copying the generated gcode to the sd card is complete before
unmounting it.  this will most of the time be quicker than 1 second,
but also will be longer if necessary.
